Product Description

About products

In the realm of severe services characterized by high temperatures and substantial differential pressures, SNT's multi-stage trim emerges as a beacon of precision and longevity. Its design ensures tailored control, standing resilient against the rigors of cavitation erosion and noise disturbances, whether dealing with compressive or non-compressive fluids. This innovative series boasts multi-faceted advantages, enhancing performance and durability which in turn leads to significant maintenance cost savings and system streamlining. The elimination of additional equipment such as diffusers and silencers further reduces expenses. From models 6862, 7500, to 9000, tailored selections can be made based on fluid conditions, balancing both functions and costs. matched with their unique capabilities and pricing structures.

The multi-stage pressure-reducing labyrinth control valve features a sophisticated core throttling component, consisting of intricately stacked metal discs lined with labyrinthine grooves. As fluid traverses these channels, it engages in repeated collisions and directional shifts, effectively dissipating energy. This intricate process masterfully governs flow rates while methodically lowering pressure, making it indispensable in specialized high-temperature, high-pressure scenarios, such as those found in nuclear and power plants. Although primarily utilized for superheated steam, it also proves versatile for liquid media.
